We show that Sihvola's counter-claim against a certain constraint on linear constitutive relations is erroneous. Pending the production of an actual sample of a non-reciprocal bi-isotropic medium, we opine that the constraint remains physically valid, besides being mathematically proper in the context of modern electromagnetic theory.
